@Lightwizard,
These are the side effects:
Back pain; blurred vision; cough; decreased sexual ability; diarrhea; dizziness; drowsiness; lightheadedness; runny or stuffy nose; sinus inflammation; trouble sleeping; weakness.
Back pain -- I wouldn't be able to judge as I have some back pain previous to taking Flomax, but it doesn't seem to exacerbate it.
Blurred vision -- no.
Cough -- no.
Decreased sexual activity -- you're kidding, or get Viagra.
Anyway, to all the rest, I can't attribute any of them specifically to taking Flomax. I became used to the blood pressure medication after a few months which would have the common side effect of dizziness.
Do you take it at bedtime or an hour after dinner?
